Studies were carried out on the recent oil spill in the Sundarbans of Bangladesh to findout the immediate impacts on the ecosystem of the Sundarbans after oil spilling. Morethan 500 km2 areas out of the total study area have been affected seriously by the oil spillcontamination on 9 December 2014. Recorded data of the physico-chemical conditions,oil content, productivity, diversity and abundance of phyto-zooplankton and benthos ofwater, and oil content in soil indicate that the water and soil of the Eastern part of theSundarbans were polluted by the oil contamination. Results also indicate that seedlings,mangrove algae, eggs and hatchlings of commercially valuable fishes, mudskippers, mudcrabs, snails, monitor lizards were affected due to oil spill. Regeneration of the Sundritrees; intertidal zone bird - ‘Masked finfoot’, common birds, fishing cat, otter, dolphins,crocodile would be affected due to the oil spill. Long term monitoring, in depth researchand proper implementation of all rules and regulations are necessary to save the fragileecosystem of the Sundarbans-the UNESCO declared world heritage site.

Over the last few decades, software security has become significant in parallel to general software testing. Previously, the scope of software security was relatively limited as compared to the software functionality. But now, in global software engineering, the scope and budget of software security are far more than its basic functionality. This has created a pressing need to devise the separate set of working boundaries between software quality testing, and software security testing in global software engineering. In the past literature, a massive number of software security testing methods has been devised. In this paper, a comprehensive literature review is presented on the recent global software security testing methods. In addition, the strength and limitation of each framework are discussed and analyzed. Finally, this work submits the open areas in the domain of global software security testing methods as one of the deliverables of this research work.
In situations where there are risks of damage to equipment or to personnel operating equipment, simulators play an important role in training operators. Once the operators develop a certain level of confidence over the simulator they can be further trained on the actual equipment. The paper describes the development of a custom build simulator for synchronising alternators, used to train operators at Yallourn TAFE College in Victoria, Australia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
